"Predestined to be conformed to His son." Are the elect, many are called but few are chosen and faithful, these will rule with Christ because He rules in them. He that has suffered in the flesh has ceased from sin. these have a crown of Life: eternal beings. Not all believers are overcomers. Some will be saves but as through fire, but lose their reward, they do not become eternal beings but remain among the nations of the saved who walk in the light of the City, The new Jerusalem. I could go on but that could be overwhelming and you only need to be fateful to walk in the Light you have to get more light.
